Wearable devices more and more infiltrated into our lives, these smart devices can not do without the support of the circuit. However, if these close-fitting equipment, hiding a root rigid circuit, the comfort of using it will be greatly reduced.
Professor Bao Zhenan, a chemical engineer, is trying to change the situation. For this situation, the choice of flexible electrode is a very natural idea.
For over a decade, her lab has always wanted to make electronics softer and more flexible, just like the second layer of the human skin. They want brittle plastics to become more conductive and flexible.
Recently, Professor Bao Zhenan published their latest achievements in Science Progress magazine. The paper describes a brittle plastic that can be chemically bent to the same extent as a rubber band and slightly increased in conductivity. The result is a soft and flexible electrode that fits nicely with our soft, fragile nerves, meaning that such circuits are on our surface and the nerves of our skin do not feel uncomfortable.
Professor Bao Zheenan very excited about the results: This flexible electrode opens up many new possibilities, such as the brain interface (implantable electronics) other aspects of the brain interface.
According to the Xinhua News Agency, Bao Zhenan said in an interview that the existing electronic devices, including electrodes and materials, are hard. In measuring the CNS current and cardiac current, the electrodes implanted in the brain or heart may damage nerves or Heart tissue. Therefore, the electrodes in contact with the nerve need to be as soft as the skin, which is an important issue to be solved in flexible electronic applications.
